| 摘 要： | 在拱坝坝肩稳定、边坡稳定计算中，有限元法是目前考虑因素最全面的数值分析方法，但缺乏明确的稳定安全指标。刚体极限平衡稳定分析法，与拱坝规范相配套，有较成熟的评价标准和广泛的应用实例。本文将有限元成果纳入到刚体极限平衡法体系里，利用其稳定安全系数指标体系，评价拱坝坝肩稳定和边坡稳定，并在锦屏一级拱坝设计中得到成功应用。

| Abstract: | Among the methods of arch dam stability and slope stability analysis, the finite element method (FEM) can take almost all factors into consideration； especially seepage，material constitutive relationship ，structure a deformation, stress distribution ,complicated material distribution and boundary contact status etc. But there is no corresponding evaluation system provided by the design code. On the contrary, there are specific indices in the rigid body limit stability analysis. In this paper, the FEM results are re-analyzed with the limit stability analysis formula, to get the similar safety factors, which could be easily compared and estimated. Finally, the method has been successfully applied to Jingpin Arch Dam design. |
